> Key: HBASE-10312
> URL: https://issues.apache.org/jira/browse/HBASE-10312
> Project: HBase
> Issue Type: Bug
> Reporter: Andrew Purtell
> Assignee: Jean-Daniel Cryans
> Priority: Critical
> Fix For: 0.99.0, 0.94.19, 0.98.2, 0.96.3
>
> Attachments: HBASE-10312-0.94.patch, HBASE-10312.patch
>
>
> Steps to reproduce:
> 1. Start a cluster.
> 2. Start an ingest process.
> 3. In the HBase shell, do this:
> {noformat}
> while true do
> flush 'table'
> end
> {noformat}
> We should reject abuse via administrative requests like this.
> What happens on the cluster is the requests back up, leading to lots of these:
> {noformat}

> monitoring.TaskMonitor: Too many actions in action monitor! Purging some.
> {noformat}
> At this point we could lower a gate on further requests for actions until the
> backlog clears.
> Continuing, all of the regionservers will eventually die with a
> StackOverflowError of unknown origin because, stack overflow:
> {noformat}
